[otrs] Upgrade from 2.1.4 to 2.3 beta4

Has anyone been able to upgrade OTRS 2.1.4 to 2.3 beta 4? I'm running OTRS on Windows XP with MySQL. I have tried to do the upgrade all last week and have been unsuccessful because the database were not in tune with each other. Does anyone have a step by step on how to transfer all info in 2.1.4 to 2.3 beta 4 in windows XP? Any help would be greatly appreciated!
